B8200HST trans questions

[rsdata]

My Kubota is probably 40 years old. I only cut an acre and a half grass on a hill normally for the last 30 years. Runs well until I drained fluid and replaced the hydraulic filter about two months ago. It now appears to act sluggish. I have to push on the forward pedal much harder then I used to to get any speed in mid-range selection. The pedal will not return to center when I release the forward/reverse pedal.

I put this fluid in to replace what was taken out. Any ideas what could be the problem?

Did you pull and clean the hydraulic screen?

That sounds like a problem with the pedal not the hydraulic system. Inspect and lubricate the linkages

Is the oil level correct?

Typically after changing it you have to run the tractor and then top it up again. Check on level ground.

I am not aware of a screen... where can I find it?

yes I have topped it off, let me re-iterate that after many years of use this hydraulic system worked fine until I decided to do this OVERDUE maintenance item... It still runs but seems sluggish now after the service

Coincidences do happen.

1. There is nothing wrong with your choice of oil.
2. The HST is self contained inside the case so the suction screen for the implement pump is not relevant.

I can not see how a simple oil change would make the trandmission "sluggish" or make the speed control pedal hard to operate. That is a mechanical linkage.

Wanna rethink your comment?
The filter screen has 100% bearing on the HST operation.
It makes the transmission sluggish because it can't get fluid flow.

It's what holds the suction line to the side of the transmission.

actually I had a younger helper when this was done and he said that YES it was cleaned and commented that it was well constructed and already pretty clean

I stand corrected.

Might want to recheck it now.
